Great price and value . I use it in My duel reactor and it works great . I get about a year out of a 2.5 # container . I use carbon every other Month in second chamber . Filter could have a larger diamater so it can hold the carbon down .

Great product, great value. Works perfect for my 135 in the BRS reactor with a MJ1200. Definitely will continue to use this product.

Cant beat the price, hight quality GFO which I know is going to help keep my phos level down at 0 and make all my coral grow like weeds

0 ppm and LOVING ITBy Aaronon 9/7/2011

Went from .22 to 0 ppm in a matter of days this stuff works! It can get stuck in the chamber ever once and a while. When it does I have to up the pressure to blow it around a bit so the tumble and restart, but I'm okay with this little step.

I bought this when I bought my brs dual reactor because money was tight. It lasted about 3 months, If I would have had the money I would have bought the 2 pound jug. It got me going and I saw a huge differance in the amount of algae on my glass. It works great and I'm hooked. If you want less phosphates and a cleaner glass and overall aquarium run this stuff from the best company in the biz.. Way to go BRS all your products are great and awesomely priced. I'm a loyal customer. BRS all the way baby!!!

Good GFOBy Andyon 8/25/2011

GFO is expensive to start with, but Bulkreefsupply is the best price I have found on the web. Very fine and tumbles easily. Works great to lower phosphate.

I Should Have Bought MoreBy Greyon 8/24/2011

So I bought the BRS GFO Reactor and MJ 1200 (don't get me started on that piece) and set everything up. As I was setting it all up, I had someone else test my Phosphate levels which were .39 ppm. That night, because it was a new test kit, I tried out the test kit myself and the levels were .19 ppm. I was sure then that the other person just didn't use the kit correctly because this isn't supposed to be an immediate cure or anything. The next morning I tested again and the phosphate levels are 0.00 ppm. This stuff is great. I should have bought more so I wouldn't have to come back a few months to replenish my supply.

I used the HC in the BRS reactor in my 85 gal tank. Though it did take almost all my algae away it was hard to dial in the reactor with the HC. I was constantly having to dial it in. It could have been user error however i currently use the Precision Marine reverse reactor with the Granuller and it works great on my 185.

good value and performanceBy Christopheron 8/17/2011

I've used other products and found for the price you can not go wrong with this gfo. This gfo helped solve my phosphate problem and dropped my levels to 0 almost overnight. Use it in a reactor which works really well.

Great!!!By Bryanon 8/11/2011

I started using this product almost a year ago. Like many of us I started without using RODI I was using distilled water or Ozarka for topoffs and saltmix. Hair algae and Phosphates soon took their unwated presence. After using this in a Reactor and using the RODI unit from this site no more algae, or nasty CYNO

prefer the pellets over the granulesBy Leeon 8/10/2011

The granules need more care in controlling water flow and tumbing to prevent the agent from breaking down and entering the water stream. The pellets seem to be more mechanically stable for use in a reactor. Both products do a fine job in scrubbing PO4 from the system.
